UK, not North Korea, source of DDOS attacks, researcher says

The U.K. was the likely source of a series of attacks last week that took down popular Web sites in the U.S. and South Korea, according to an analysis performed by a Vietnamese computer security analyst.

The results contradict assertions made by some in the U.S. and South Korean governments that North Korea was behind the attack. Security analysts had been skeptical of the claims, which were reportedly made in off-the-record briefings and for which proof was never delivered.

The week-long distributed denial of service attack involved sending multiple requests to a handful of Web sites from tens of thousands of computers so the sites became overloaded. Among the sites taken offline at some time during the week were those of the U.S. Departments of Transportation and Treasury, the U.S. Federal Trade Commission, the South Korea's president's home page, the South Korean national assembly and U.S. Forces Korea.

The computers used to send the flood of requests had been infected with a virus that allowed attackers to use them anonymously.

Every three minutes the infected computers randomly selected one of eight servers to connect to and receive orders, said Nguyen Minh Duc, senior security director at Bach Khoa Internetwork Security (Bkis), in a blog posting on the company's Web site. Bkis says it gained control of two of the eight servers and through this has been able to discover the master server.

That server has an IP address in the 195.90.118.x range, Nguyen said.

The address is registered to Global Digital Broadcast in the U.K. The company could not immediately be contacted.

"Having located the attacking source in UK, we believed that it is completely possible to find out the hacker," Nguyen wrote.

Through analyzing the log files of the two servers it controls, Bkis said the attacks utilized 166,908 PCs in 74 countries that had been infected. That figure is significantly higher than the "several tens of thousands" that other security companies had estimated were involved.

The largest number of infected PCs were in South Korea followed by the U.S., China, Japan, Canada, Australia, the Philippines, New Zealand, the U.K. and Vietnam.

I kind of figured the NorKs weren't behind it when their IT guys have their 14.7k modems hooked to these thing still...

Snippet from post no. 1:

"That server has an IP address in the 195.90.118.x range, Nguyen said. The address is registered to Global Digital Broadcast in the U.K. The company could not immediately be contacted. "Having located the attacking source in UK, we believed that it is completely possible to find out the hacker," Nguyen wrote."

1812 was a draw. This is for stealing Catherine Zeta-Jones!

I mean, really! They went to a lot of trouble to chase Congress out of the Capitol and burn down the White House, and did anybody even do so much as say "Thank you"?...

Well as you know, I’m not a geek, but a kind emailer sent me some tech stuff in plain english that even I can understand; and I’ll sum it up in my own words:

The article on this thread is interesting, but, bottom line — it still does not mean that the North Koreans aren’t responsible for the latest attack.

So what? Bern and Zurich in Switzerland are HOTBEDS of North Korean intelligence activities, with agents and computers and embassy personnel all over the place, who base many of their illicit activities out of there (through dummies such as the KFA, etc. etc. etc.). There is no doubt in my mind due to who and what was attacked, that (even with intermediary zombie computers), the trail will most likely eventually lead to Pyongyang.

Really. you hijack a server in England for convenience. No need to have your slaves report back to a box that reports to you when you can add another layer of stealth.
